IMPROVEMENT IN AXLE-BOX PRESSES.

Specification forming part of Letters Patent No. 222,646, dated December16, 1879; application filed May 14, 1879.

To all whom it may concern:

Be it known that we, HENRY BACON AN- nnnws and OSCAR WILLIAM BALL, ofFaribault, in the county of Rice and State of Minnesota, have invented anew and useful Improvement in AX16'BOX Presses, of which the followingis a specification.

Figure l is a vertical section of our improved machine. Fig. 2 is a topview of the same.

Similar letters of reference indicate corre' sponding parts.

The object of this invention is to furnish a machine for pressing theaxle-boxes into the hubs of wheels which shall be simple inconstruction, strong, durable, and convenient, and effective in use,tbrcing the axle-boxes to their places without any danger of breakingthem.

The invention consists in the combination of the bed plate or frame,having a large hole or opening through its center, the detachable plate,having a hole through its center to receive the end of a hub, thestationary uprights, the detachable cross-bar, the screw, and the lever,with each other, as hereinafter fully described.

A represents the bed plate or frame of the machine, which has a holeformed through its center a little larger than the largest hub to beoperated upon. B is a plate, which is rabbeted upon the lower side ofits outer edge to fit into the hole in the plate or frame A, and whichhas a hole formed through its center to receive and lit upon the smallerend of the hub that is to receive the axle box, the spokes of the wheelresting upon the upper side of the said plate B. Several plates B shouldbe provided with different-sized holes through them to'correspond withthe size of the different hubs to be operated upon.

To the'bed plate or frame A, upon the opposite sides of the hole throughits middle part, are securely attached the lower ends of two uprights,O, which have screw-threads formed upon their upper ends toreceive thenuts 0, two to each.

D is a strong cross-bar of such a length as to reach from one to theother of the uprights (J, and the ends of which are placed upon theupper ends of the said uprights G, between the nut c. longitudinally,and the other end is notched to receive the upper ends of the uprightsO, as shown in Fig.2, so that by loosening the upper nuts, 0, the bar Dmay be slipped back and swung around to allow the wheel to beconveniently placed upon and removed from the machine.

Through the center of the bar D is formed I a screw-hole to receive thescrew E, the lower end of which is rounded oil, and to its upper end isattached a lever, F, by means of which it is operated. I V

In using the machine the wheel is arranged upon themachine ashereinbefore described, the axle-box is inserted in the bore of thetube, and started in by a few light blows with a hammer or mallet. Aniron block is then laid upon the outer end of the axle-box, the bar I)is swung into place and secured by tightening the upper nuts, 0, and thescrew E is turned down, forcing the axle-box into place. If desired, oneend of the cross-bar D may be hinged to the upper end of one of theuprights G, and its other end secured to the upper end of the otherupright by means of a socket or hole and pin, so that it may beconveniently released and turned back; or the said cross-bar may besecured in any other desired way that will allow it to be convenientlyreleased and turned back.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The combination of the bed plate or frame A,having a large hole or opening through its center, the detachable plateB, having a hole through its center to receive the end of a hub, thestationary uprights G, the detachable cross bar D, the screw E, and thelever F, with each other, substantially as herein shown and described.
